i got banned from sc2 today for aparantly using hack programmes now i have never hacked in my life so i researched further and the culprit is RAIDCALL it's like ventrilo or teamspeak and aparantly it uses an overlay to run which is simular to what hackers use, so if anyone plays starcraft and uses raidcall do not open raidcall when u are playing as me and lots of my guildies in wow got banned from SC2. u can even google "banned starcraft 2 Raidcall" if u dont believe me hope this helps.
